Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed July 30, 1903. Serial No.167,527.

To rtl/f whom, it 7am/y concern:

Beit known that I, JASON C. LOTTERHAND, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in a CombinedAddin and Type-Writing Machine, of which the following is aspecification.

This invention relates to an addin -machine adapted,- to be independento but placed adjacent to a type-writing machine and provided withintermediate mechanism whereby the adding-machine becomes temporarilyand so long as the connections are maintained an integral part of thetypewriting machine.

Heretofore calculating mechanisms have been attached to type-writermechanisms to form a part thereof; but they were not, so far as known tome, separable therefrom and were not adapted to be used with othertypewriting mechanisms of different construction. In this invention, onthe contrary, the adding mechanism is adapted to be actuated by anytype-writin mechanism comprising numeralkeys, with s ight changesconforming merely to the variations of the key connections on thetype-writing machine. The adding-machine which it is preferred to use inthis connection is the one on which Letters Patent of the United StatesNo. 718,486 were issued to me January 13 ,1903, and reference is made tothat patent for a detailed description of the parts of that mechanism inwhich no alteration has been made, and this description will not berepeated here.

It has been found most convenient in practice to place the type-writingmachine above the adding-machine mechanism, so that the former mechanismrests upon the casing or frame carrying the latter mechanism; but whileit is essential that the two mechanisms should be adjacent thisparticular relation is not necessary, as they mi ht be differentlyplaced and yet fall within t e scope of the invention. The inventionwill be described assuming the mechanisms to be placed in these relativepositions.

In the drawings, Figure 1 is a side elevation and partial verticalsection of the typewriting and adding mechanisms and their connections.Fig. 2 is a partial horizontal section and a plan view of some of theparts. Fig. 3 is a rear elevation of the combined mechanisms. Figs. 4and 5 are details of the denomination mechanism. Fig. 6 is adetail ofthe type-writer key-lever finger. Fig. 7 is an enlarged top plan View ofthe rear ends of the oscillators beneath the plane of the springs 7 9.Fig. 8 is an enlarged rear elevation of the parts shown in Fig.7,concealed parts being shown in dotted outline. Fig. 9 is an enlargedside elevation of the parts shown in Figs. 7 and 8. Fig. 10 is anenlarged top plan view of the mechanism at the rear of the machinedirectly beneath the type-writer key-levers. Fig. 11 is an enlar eddetail view of the parts shown on a smal er scale in the lowerright-hand corner of Fig. 1. Fig. 12 is an enlarged elevation of theparts relat ing to the adding mechanism shown mainly in dotted outlinein Fig. 1. Fig. 13 is an enlarged perspective view of the parts shown inFig. 10 looking from the rear at the right and above with the casingremoved. Fig. 14 is a detail perspective view of the universal frame.Fig. 15 is a detail sectional elevation of the rear end of adenominational oscillator and adjacent parts. Fi 16 is a detail top planview of substantia ly the same parts. Fig. 17 is a detail rear elevationof the intermediate lever. Fig. 18 is a detail side elevation of thecentral part thereof. Fig. 19 is a rear elevation of the parts shown inFig. 13. Fig. 20 is a detail view of part of the mechanism of Fig. 19,and Fig. 21 is a detail view of the leader and intermediate lever.

The type-writing mechanism shown is what is known as the Underwood, butany other practical mechanism may be substituted therefor.

In the drawings, 10 is the adding-machine of the construction referredto, and 11 is its casing. The only alteration made in this constructionis that the key-tops are removed and the key-stems are adapted to beoscillated. The adding mechanism is set in a supplementary casin 20,consisting of a rear wall 21, side wal s 22, a bottom 23, coincident inpart with the bottom of the casing 11, and a top 24, provided with twoapertures, one, 24a, near the front to permit of the passage of thetype-writer numeral-key levers or their fingers, as the case may be, andthe other, 24h, near the rear to permit of the passage of the lowerportion of the universal frame.

The t e-writing mechanism 30 (hereinafter ca led the type-writer) is ofusual form and provided with keys, a platen-roller,

IOO

carriage, ink-ribbons, and the other arts common and necessary tomachines o this character and needs no further or particular descriplion.

As has been stated above, the adding-machine is unchanged except for theremoval of the key-tops and the adaptation of the keystems to beoscillated. It is necessary to provide an operating mechanismintermediate the type-writer keys and the stems of the adding-keys toactuate the latter. This mechanism consists, primarily, of twoartsfirst, means adapted to reciprocate the adding-key stems consistingof digit-hails transversely hinged across their tops, and, second,

vmeans for moving the digitails consisting of lingers or.extension-pieces attached to the type-key levers and adapted to strikethe digit-hails as the type-bars are depressed.

The digit-bails 40 each consist of a straight bar 41, passing abovetheto s of the addingkey stems 200 and suspen ed by members 43 43,mounted in bearings in the sides of the casing 21 and held in an upwardposition by a coiled spring 44 against a stop-bar 45, mounted betweentwo of the combs 46. This spring 44 passes around an arm 47, secured toone of the members 43. These digit-hails correspond in number to thenine rows of the adding-key stems, each bail being adapted to actuatethat one of the series of key-stems beneath it correspondin in value tothe type-writer key depresse It might be possible so to construct atypewriter that the numeral-keys could be arranged when depressed todirectly strike the digit-bails; but no standard machine is made thatway. It is therefore necessar to provide means interposed between t etypewriter keys and the digit-bails which will insure the depression othe latter when the proper digit type-writer key is depressed and whichwill not act upon the bails at all when any key other than a numeral-keyis depressed. Such means in the mechanism illustrated consist ofthefingers or extensionpieces 420, which may be made of any suitable sizeand material so long as they are secured to the type-writer keymechanism and extend from some one of its moving parts to such aposition with respect to the proper bail that when depressed it willdepress such bail. The form of the finger illustrated consists of twoleaves 421 and 422, adapted to embrace the key-lever and to be retainedin position thereon by its own inherent elasticity.

The keys of the adding-machine are slightly different in constructionfrom the form shown in the Letters Patent No. 718,486 above referred to.These iin ers are preferably made removable in order that thetype-writer may be restored to its original condition if it is no longerdesired to employ the adding mechanism in connection therewith; but whenonce the fingers are in place they must be rigid in order to accomplishtheir purpose, and if it is intended always to use the adding mechanismwith the particular type-writing machine the may be made integral withthe numeraleys. The key-stems 200 (best shown in Fig. 1) are eachvertically slotted at 201 near their upper extremity and are narrowed at202 to admit of the passage of the digit-bails between them. Theconverging oscillators 450 (presently to be described) are each providedwith a series of projecting pins 451, engaging in the slots 201, so thatwhen any one of these oscillators is moved forward the entire row ordenomination of addingkey stems 200 corresponding to this oscillator isswung forward to bring the narrow tops 202 underneath the series ofdigit-baile, so that when ,any one of the latter is depressed by thedepression of a type-writer numeral-key the corresponding adding-keystem is depressed. The conver ing denomination oscillators 450 are longars, nine in number, supported in a series of combs 46, transverselymounted across the frame of the casing 11 and the reciprocation of whichoscillators swings the row of correspondin keystems into actuatingposition. The a dingkey stems 200 are normally out of an operativeposition, bein so arranged that when any bail is depresse it passesfreely between their upper extremities. It is necessary, therefore, torovide means for bringing them into sue a position that their tops shallbe brought into line with the typewriter key-ngers and the digit-bailebefore a digit-bail is depressed. For this purpose there is rovided auniversal frame 50, consisting o a bar 51, sup orted at the extremitiesof a pair of bel -crank levers 52 52, mounted on opposite sides of theframe 210, and a rod 53, supported at the other extremities of the samelevers 52 52, which are hinged to swing on suitable 'ournal-pins 54,secured to the frame 21 or ormed thereon. There is also provided acarriage 60, which in the form illustrated travels on wheels 61 61,mounted between rails 62 62, secured in any suitable manner to the frame21 and which is provided with ears 63 63, forming bearings or a pivot64, on which is swung a lever 65. The lower end of this lever hangs nearto the rod 53, and the upper end of it is forked at 66 to carry a finger67 which is adapted to be brought into contact with that one oftheE`converging oscillators which is selected by thedenomination-lever.presently to be described. The type-writer carriageand the carriage 60 each moves an identical distance at each step, andconse uently the iinger 67 if rigidly secured to t e carriage 60 wouldstrike .the next denomination-oscillator before the typewriter hadfinished its stroke, because while the centerlines of the oscillatorsare the same distance apart as the successive positions of ICO IXO

ISO

the carriage, vet theI linger (i7 if projected inlo the space lbetweenthel oscillators would, owing to the thickness oli the oscillators andthe consequent reduction ol' the space between them, strike thedenommation-oscillator next to that upon which the linger had lastdelivered its stroke and lrom which it was being withdrawn. ',lo obviatethis, the Vl'ork (SG is provided. transverse bar 660, around which iscoiled a spring ($61 to all'ord a laterally-yielding bearing for the arm(i7 until the latter has had lime to return to its proper position tostrike the next dcnomination-oscillator to record the next digit in theseries. It is obvious by means ol' this mechanism that when the bar 5lolt the universal frame 5() is depressed, for example, by the downwardmovement of any ol' the type-writer key-levers the rod 53 will be swungto contact with the lower member of the lever 65, the finger 67 will bemoved forward, and if the carriage is in position will move that one ofthe converging oscillators in line with it forward to bring theadding-key stems and digit-hails into line. The bar 51 is depressed bythe downward motion of any of the type-writer key-levers, as they allare brought into contact with it. Therefore the lever will be constantlyreciprocated as the type-writer keys are moved; but this has no ell'ectupon the adding mechanism unless the type-writer carriage is in a ro crposition. When the movement of tlie ar 51 is caused by the depression ofany of the typewriter numeral-keys, the parts are so constructed andtheir movements are so timed that the oscillator is moved to place thekeystems in alinement before the finger 420 on that particulartype-writer key has struck the digit-bail to depress the properaddingkey-stem.

The means employed to place the carriage 60 into the proper actuatingposition so that the converging oscillator required to swing forward thedesired addin key. stems be in operative position are as fbllows: Aseries of levers 70 70, (called denomination-1evers on account of theirpeculiar function,) corresponding in number and position with the seriesof converging oscillators, are each pivotally mounted in suitablebearings on the front of the frame, being normally held outward bycoiled springs 71. A leg 72 of any one of the levers 70 is adapted to bebrought into contact with a pin 73, projecting laterally from theconverging oscillator, and thus to move this oscillator toward the frontof the machine. Each oscillator is provided with a projecting pin 74 orsimilar means for engaging with one of the oscillating levers 75, (onebeing provided for each oscillator,) hinged to swing upon a pivot 76,secured to any suitable point in the framework, so that when thedenomination-lever 70 is moved the lever 75 is moved a corre- 'lhis'fork carries a spending distance, a coiled spring 750 serving toretract it to place and spacing-collars 751 keeping thelevcrs 75 apart.Supported in fixed guides 77 77 in thc 'frame of the machine are placeda series ol oscillating stopbars 7 77, one for cach convergingoscillator. Each bar 777 is notched at 7 8 to receive the lowerextremity of the lever 7 5, and each bar is reciprocatcd as the lever 75 is swung. The converging oscillators are placed at the front end ofthe machine to coincide with the position of the rows of the ad ding-keystems and are then deilected and caused to converge, so that at the rearend they are s aced to coincide with the teeth of the rac of thetypewriter carriage. A coiled spring 79, secured to each oscillator andto a iixed part of the frame, serves to retract it to position after ithas been moved. Any oscillating stop-bar 777 being thrown out ofalinement and beyond the plane of its normal position when at rest bythe action of the lever 75, the oscillator and the denomination-leveristhen thrown in the path of a lug 68, forming part of the carriage 60,and prevents its further movement toward the left, Figs. 3, 10, 13, 16,'

and 19.

Itis obvious that the space on the paper in the type-writer on which arerecorded the impressions of the numeral type-bars whose levers can beactuated to set in operation'the adding-keys constitutes a zone withinthe area of which the adding mechanism and the recording mechanism ofthe type-writer have become united and that the position of such zonevaries with respect to the paper in the type-writer at the will of thetype-writer operator who may desireto add numbers recorded at any partof the sheet. The means employed to control the position of this addingzone are as follows: A rail 80 is secured to the type-writer carriage bytwo brackets 81 81, in which it is journaled to swing on trunnions 82 82to permit of its passing by the intermediate lever (presently to bedescribed) upon the return of that carriage;

Mounted upon the rail 8O is a movable leader 83, consisting of a frontflat member 84 and a rear member 85, the groove being adapted to embracethe rail. A beveled lug 86 on the inside of the leader 83 is secured toor made integral with the member to engage with the intermediate lever.It is also provided with a toothed lock 87, adapted to be placed in andout of engagement with the teeth on the rail by a yielding button 88,secured to its outer extremity and projecting from the face of theleader 83. By this means the leader 83 can be set in position alon thetype-Writer carriage and retained in suc position after adjustment.

An intermediate lever 90 is pivotally mounted upon a hub 91, secured toa bracket 92 or any suitable fixed part of the rear frame of thetype-writer. This lever 90 is IIO composed of two members, the outer one93 being movable upon the inner one 94' by means of slots 95 95 andstops 96 9,6. This arrangement rovides a means for releasing the lever90 om its engagement with the leader 83 when the carriage is about topass out of the adding zone. The upper end of the outer member 94 of thelever 9() is so placed that it is within the path of the leader 83 asthe carriage of the type-writer is moved to the left of the operator andis adapted to be intermittently moved upon its pivot as the carriagemoves step by step. The lower end of the inner member 94 of the lever ispivoted at 94() to a link 610, secured to the carriage 60 by a stud 611.From this it is evident that as the leader 83 moves step by step to theleft the carriage 60 must also move step by step to the right. Thiscarriage, however, it will be remembered, carries the finger 67,- whichmoves the converging oscillator of the highest denomination selected tobe recorded to bring the adding-key stems in coincidence with thetype-keys to register the values recorded by the latter. Therefore theposition of the leader 83 determines the position upon the papertransported by the carriage of the type-Writer at which the numbers tobe registered by the adding mechanism are recorded, or, in other words,it fixes the position laterally of the adding zone, the lon itudinalposition of this zone being fixed by t e rotation of the papercarryingplaten. The member 93 is also the releaser for the lever 90 and loc-kingdevice for the keys, hereinafter described.

The intermediate lever 90, the carriage 60, and adjacent parts are in anoperative position, as illustrated in Fig. 3, and after the numbers havebeen written upon the paper and thus recorded and the appropriateadding-key stems have been simultaneously actuated to register suchnumbers the operating-bar 100 of the adding mechanism is actuated toproduce the total of the different numbers recorded, which total isdisplayed y upon the appropriate wheels, as described in i the patentabove referred to, and may then be read off and written upon thetype-writer in the usual manner.

A bar-lever 110, Figs. 1, 11, and 12, is fulerumed at about itsmid-length to any suitable part of the machine-frame and is secured toor made integral with the adding-bar 100 at its front end. At itsrearend it is rovided with a pin 1 11, which engages in a ork 113 of a lever112, pivoted at about its midlen th and which at its rear end isprovided wit a transverse rod 114, supported at its other end by a crank115, suitably pivoted. This rod 114 is adapted to engage with a hook 98,formed at the lower extremity of the outer member ofthe lever 9() bybending its parts, as shown in Fig. 17 and in dotted lines in Figs. 1and 11 to depress the lever 90 and sims? throw it out of engagement withthe leader 83, and thus permit the carriage of the typewriter to proceedand the carriage 60 to be retracted to its normal position.

Transversely mounted to slide in suitable bearings in the frame of thecasing 21 is a rod 120, carrying two hooks 121 121, one at each end,rividly secured thereto and in proximity to the lower members of thebell-crank levers of the universal frame. This rod 120 is longitudinallyslotted at 122'to receive a tongue 123, de ending from the carriage 60,the slot 122 belng so arranged in the rod that the tongue 123 touchesone extremity of the slot as the units of cents is recorded, so that themovement of the carria e of the type-writer (and consequently of t ecarriage 60) one step farther will cause the tongue 123 to move the rod120 to brin the hooks 121 121 closely to embrace and hold the bell-cranklevers, and as these levers determine the motion of the bar of theuniversal frame, which bar is in contact with all of the key-levers, allof these key-levers are locked against any further movement until thehooks 121 121 are moved out of engagement with the frame. The rod 120 isrestored toits normal position by the coiled spring 124.

The movement of the operating-bar 100 of the adder is necessary tounlock the parts and permit the Writing to proceed. Such movementdepresses the o erating-bar levers 110, which in turn trips t e lever112 and carries down the transverse rod 114, and this in turn depressesthe movable part 94 of the intermediate lever 90 and releases the sameto permit the carriage 60 to return to its normal postion and thetype-writer carriage to procee An air-check is provided to eliminate theshock occasioned by the impact of the typewriter carriage against theintermediate lever 90 whenever the travel of the carriage isconsiderable before it reaches the lever. This air-checkY consists of ac linder 600, secured at a suitable oint witllin the framework, and aloosely-fitting piston 601, adapted to reciprocate therein and which isprovided with a piston-rod 602 secured at any suitable point on thecarriage 60. If the lever 90 is struck quickly or violently by themovement of the type-writer carriage when the carriage is released andthe carriage 60 is thus moved quickly to the left, such movement istaken up by the. air-check, which also serves to diminish noise andshock arising from the movement of the carriage 60 or its actuatingarts.

At the back of the inner member 94 of the intermediate lever 90 there isa pin 97, to which is attached one end of a spring 988, coiled aroundthe hub 91, the other end of the spring being secured to the bracket 92at any suitable point, as the pin 99. When the lever 90 is moved by theleader 83, this IIO mechanism, which are locked until this bar is ldepressed to release them.

To the outer member 93 ofthe intermediate lever 90 is secured adependent flaring Ainched spring 930, the lower extremities. o lwhichembrace the hub 91. When the rod 114 is actuated to pull down the lever90, this spring 930 is forced down over the hub and is adapted, byreason of its construction at 931 to embrace it in its new position toretain it positively in place, making its movement positive and certain.The oscillating stopbars 777 are arranged in a series corresponding innumber and position to the denominations vof the numbers tov be recordedand added. A difficulty arises from the fact that the decimal-point mustbe recorded before the tens of cents when the figures represent monetaryvalues. It is necessary to stop the carriage 60 at the place where thisdecimalpoint must be written.- The oscillating stopbar 7 77corresponding to tens' of cents is therefore offset at its extremity778, so that the movement of the type-writer carriage is arrested atthat point and the adding operation suspended while the decimal-point isbeing recorded.

The method of using the machine is as follows: The fingers orextension-pieces 420 are first placed in their proper positions upon thedifferent numeral-levers of the type-writer.

` The type-Writer is then placed above the as usual.

adding mechanism, a proper registration being secured by lacing therubber feet of the type-writer in epressions 222 in the addingmachineframe, formed therein for that purpose. The bracket. 92 'is thensecured, b

screws or whatever other means is provide to the rear frame of thetype-writer, and the rail 80, with the leader 83, is similarly placed inposition. The intermediate lever is then swung around and the link- 610is secured to the carriage by means of the stud 611 or what othersuitable means has been provided. These operations couple the type-Writing mechanism to the adding mechanism.-

Now let us suppose that it is desired to write on the type-Writer, say,three items of an invoice and add the items, and let the items, forinstance, be as follows:

750 yards of black silk $4.00. $3,000.00

The Words 750 yards of black silk $4.00 would be Written on thetype-Writer If the words were begun at 10 on the type-Writer scale,$4.00 would terminate at 40.v It would probably be desirable with a lineof that length to have the adding front, and depresses it. 'that one ofthe adding-key stems which has zone begin at 55 on the scale. The leader83 Would then be set at 55, and thereafter needs no attention. It willbe' observed that the first item to be added is $3,000.00, the highestinteger being in the column of units of thousands. After the line hasbeen written to the point above mentioned it is necessary to pressinwardly that one of the denomination-levers corresponding to thefigure, and in the form of machine illustrated this would be the sixthone, counting from the right, and the fourth one, counting from theleft. This movement of the lever 7 O draws forward the correspondingconverging denominationaloscillator 450. This in turn, through the pin74, moves the oscillating lever 75, Which in turn moves in the notch 78of the stop-bar 777 and projects this bar into the path of the lug 68 onthe carriage 60. (See Fig. 9.) If the type-Writer carriage is now.because the bar 450 having been drawn forward the selected row ofadding-key stems have been moved into a vertical position. When,therefore, the numeral-key 3 of the type-writer is depressed, the finger420, secured to its lever, is moved downward, impinges upon the thirddigit-bail 40 from the This in turn strikes been brought into verticalposition-that is, the one in the unit of thousands columnand depressesit. When the lever 70 has been (pressed and the type-writer carriagerelease the carriage 60 is, as has been explained, brought into properposition, so that the type-Writer carriage and paper is in such aposition that when the first integer of the number is struck it Will bein the column appropriate to units of thousands. The operator releasesthe lever 70 as soon as he observes that the type-writer carriage hasmoved to its proper position. When the numeral type-writer key-lever isdepressed, it depresses the universal frame 50. This in turn pressesinward the lever and arm 67, Whlch latter moves forward, strikes againstthe particular denominational oscillator in front of it, and thus bringsthe desired adding-key stem in alinement with the proper digit-bail tobe moved by the latter when the numeral-key of the type-writer isdepressed. The remaining integers of the number 3,000.00 being all zerosand the O-key on the type-writer not being provided with an extensionfinger-piece 420 as these successive zeros are struck and the car- IOCIOS

i riage 60 moves in step-by-step unisonwith the type-writer carria e thearm 67 moves forwar at each step an moves the corresponding oscillator450 and throws the proper row of adding-key stems into alinementsuccessively; but as the di 't-bails are not depressed nothing occurs toa ect the adding-machine, although the successive zeros are written onthe paper on the type-Writer carriage. Supose now that the operatorbeing careless or orgetful strikes a numeral-key beyond the column ofunits of cents or desires to write something-for instance, the Wordneton the same line. As the last integer of the figure 3,000.00 has beenstruck, the tongue 123 has been moved forward and the hooks 121 121 havelocked the universal frame 50 up against the entire set of key-levers,and therefore the keys cannot be depressed. This calls the attention ofthe operator to the fact that the numeral has been completely Writtenand that the operating-bar 100 should be actuated. As soon as the Abar100 is depressed the lever 112 is tripped and the movable part 94 of theintermedlate lever 90 is depressed and the carriage is released toreturn to its normal position. It will thus be seen that the adding zoneterminates at units of cents and that anything may be written on thepaper t'o the right'of that zone as soon as the operating-bar 100has-been actuated. The operator then writes the next line of the invoicedown to the number-3.15. He then presses the denomination-lever in thecolumn of hundreds and releases the type-writer carriage until the lug68 brings the carriage to a stop against the stop-bar 777 of thevdenominational lever aiected. He then writes the number 298.45, and asthe type-writer carriage'moves forward step by step and the carriage 60moves in unison with it each denominational oscillator 450 is moved insuccession by the arm 67 to throw the proper row of adding-ke stems intocoperation with the digit-bai s as they are successivel depressed by thelingers 420 on the numera keys, and when the number has been completelywritten the operating-bar 100 is again depressed. The third line of theinvoice is then written, only after the number 5.17 has'been written thedenomination-lever 70 corresponding to the tens-column is depressed,because the highest integer ofthe number 41.36 is to be written in thatcolumn. After that number has been written and the operating-bar 100depressed the total of the sums added is read from the registeringdevice provided for that purpose, and the total read from such re try iswritten beneath the sum added in t e usual manner, its proper place inthe adding zone on the paper eing fixed by pressing the properdenomination-lever corresponding to the hi hest integer of the total andreleasing tie typewriter 'carriage until the stop-bar brings thecarriage 60 to rest, and thus fixes the position of the ty e-writercarriage.

It w11 be noticed that by means of the mechanism above described it ispossible to write on the paper not only beyond the column of figures tobe added, but also to Write more than one such column of figures withintermediate text on the same .horizontal line,

4because the depression of the actuating-bar of the adding mechanismreleasing the intermediate lever 90 from its connection with the movablelever 83 enables the type-writing mechanism to be employed after suchrelease in the normal Inanner. Another feature of the mechanism is thatthe strength required to depress the numeral-keys when the addingmechanism is employed is so little, if any, greater than that requiredfor the depression of the ordinary keys that the dilference is notnoticeable.
